Shift + mouse wheel to scroll horizontally.

[Restricted18]

How do I use Shift+mouse wheel to scroll horizontally?
I want to do this operation like in Cad or Browser.
(TE's split screen and tree folders are useful, but scrolling sideways is frequent.)
I set S8,S9 in add-on Mouse but could not find horizontal scrolling.

add these 2 records:

They send ^{Left} (Ctrl+Left) / ^{Right} (Ctrl+Right) keys to a folder tree to scroll horizontally.

The settings for file lists are a bit complicated. Shift+Left and Shift+Right keys are used to scroll horizontally in Details view, but are used for selection in other views. Therefore Shift+Wheel will be ignored for other views.

FV.Focus();
if (FV.CurrentViewMode == FVM_DETAILS) {
	wsh.SendKeys("+{Left}");
}

FV.Focus();
if (FV.CurrentViewMode == FVM_DETAILS) {
	wsh.SendKeys("+{Right}");
}

(updated for multiple panes)

Thank you for your excellent response.
This is exactly the setup I was looking for.
My deepest thanks to ccfs.

The file lists setting seems to sometimes move up and down at higher wheel speeds. Also, I would like the amount of movement to the left and right to be about 4 times greater than that caused by these settings, so perhaps it would be better if they were implemented natively in TE.

Anyway, thank you very much.
I will close this issue.

You can specify the number of times to repeat a keystroke, e.g. ^{Left 4} / ^{Right 4} / +{Left 4} / +{Right 4}.
I also get the file list moving up and down problem. This may be a problem of TE.

I have finally solved the file list moving up and down problem. Here are the updated setup:

FV.Focus();
setTimeout(async function () {
	if (FV.CurrentViewMode == FVM_DETAILS) {
		wsh.SendKeys("+{Left 4}");
	}
}, 99);

FV.Focus();
setTimeout(async function () {
	if (FV.CurrentViewMode == FVM_DETAILS) {
		wsh.SendKeys("+{Right 4}");
	}
}, 99);
